Disclosure: DeDanix builds DeDanix Quote Builder for WooCommerce. These fields are practical evaluation criteria, not a claim that every store needs the same process.
Most quote delays are not caused by calculation. They happen when a request arrives without the product details, quantities, contact information or context that someone needs to answer it correctly. A good WooCommerce quote workflow makes the necessary details visible from the first request.

The essentials to capture
Products and variations
Use the WooCommerce catalog as the reference point. Product and variation search reduces ambiguous free-text requests and keeps the request tied to what the store actually sells.
Quantity and totals
Quantity controls and tax-aware live totals help both parties see what the request means. They do not replace a commercial decision, but they prevent basic confusion.
Customer context and notes
Collect the contact details and note field that your sales process genuinely needs. Do not collect data merely because a form can have more fields.
Status and review access
Staff need a clear status-management view, and customers benefit from a dedicated account area to review their requests and available documents.
Documents should be traceable
When a quotation is issued, a PDF document and a stable revision history make it easier to see what was presented. Confirm how a tool stores issued documents and what happens if a request changes later.
How DeDanix Quote Builder supports the workflow
The Free edition of DeDanix Quote Builder for WooCommerce includes product and variation search, quantities, tax-aware totals, quote administration, immutable issued revisions, integrity-checked PDF documents and a My Quotes account area. It does not include automated quotation emails or shipping estimates; those belong to the separate Pro add-on.
